The 1977 Clean Air Act and the 1998 Regional Haze Rule were created to help improve air quality in the national parks. But thanks to loop holes in those pieces of legislation, clean-up is going much slower than expected. The NPCA's petition to the President encourages him to close those loop holes and hold polluters responsible for their actions. By taking these actions it is hoped that the air quality can being to improve much sooner. To add your name to the petition, click here.
As someone who happens to love America's national parks I have to whole heartedly get behind this petition. The parks are some oft he best outdoor playgrounds in the world and they really should be protected for future generations to enjoy too. I'm encouraged to hear that air quality is improving but it is sad to hear that it could take up to ten generations to get them back to their natural state. If that is as unacceptable to you as it is to me, then click on the link above and add your name to the petition.
